Step 1. In the main interface of the iPhone data eraser, navigate to the left column to select the "Erase Private Data" option. In the opened window, you can see the file types that can be erased.
Step 2. Click "Start", and the data eraser will start to analyze and scan your device. You can stop analyzing if needed.
Step 3. After the scan is finished, all your device's data will be shown in the program interface. You can click any data to view details.
Step 4. Now check the files you want to erase, and click the "Erase Now" to delete them. In the pop-up window, type "delete" to confirm and start erasing iPhone, iPad or iPod.
You'd better erase private data on your phone regularly to protect your private information.
